Title: SitOnHands — voluntary timed IMD lock (no early exit)
Title: SitOnHands — voluntary timed IMD lock (no early exit) One-liner: Users deposit IMD and choose a lock period; funds are forcibly held until that period ends — no early withdraw, no admin bailout of user deposits. Chain: Ethereum mainnet (IMD existing token). Pair / deploy against the live IMD ERC-20; do not mint a new token. What to build SitOnHands.sol — a non-upgradeable lock vault for IMD only. User calls lock(uint256 amount, uint256 durationSeconds) (or lockUntil(uint256 amount, uint256 unlockTimestamp) — pick one and stick to it). Transfer IMD in via transferFrom; create a position per deposit (support multiple concurrent locks per wallet). While locked: no withdraw, no transfer of the position, no emergency withdraw for users, no owner sweep of user balances. Only withdraw(uint256 positionId) (or equivalent) after block.timestamp >= unlockTime, returning the exact locked IMD to the depositor. Optional: emit Locked / Withdrawn with depositor, amount, unlockTime, positionId. Optional read helpers: positionOf, unlockTime, lockedBalance, canWithdraw. Rules / constraints IMD address must be constructor-immutables (or a single immutable token). Enforce min/max duration (e.g. min 1 day, max 4 years) — document constants in the contract. Reject zero amount and zero/invalid duration. Reentrancy-safe withdraw (checks-effects-interactions or OZ ReentrancyGuard). No fee on lock or unlock unless explicitly specified (default: 0 fee). No reward / staking yield in v1 — pure sit-on-hands. Owner (if any) may only pause new locks, never seize or shorten existing locks. Prefer no owner if the factory allows a fully immutable vault. Do not add “sit on hands” marketing site unless asked; contract + tests + brief README is enough. Tests (Foundry) Lock then withdraw after warp succeeds for full amount. Withdraw before unlock reverts. Two positions for same user unlock independently. Cannot drain others’ positions. Min/max duration bounds enforced. Max duration = 365 days Out of scope Governance, voting escrow (ve), boosts, LP locks, cross-token locks, forced lock of third parties (only the caller’s own IMD). Any sell/transfer restriction on the IMD token itself (locking is deposit-based only). Acceptance Compiles; Foundry tests pass; verified deploy script ready for mainnet IMD address; public lock + time-gated withdraw only.
